Washington Governor Jay Inslee Wednesday signed legislation aimed at helping workers at the Hanford nuclear reservation. The law will allow workers who have been exposed to toxic chemicals or radioactive waste more easily access compensation for medical treatment.

As many as 11 workers may have ingested or inhaled radioactive contamination at the Plutonium Finishing Plant demolition site at Hanford in southeast Washington state. Ten workers are confirmed to have tested positive and one needs more testing to confirm the results.

Top state health officials are concerned that radioactive waste in the air is spreading around the Hanford site in southeast Washington. It’s mostly from that same demolition site that’s contaminated two workers, dozens of vehicles and closed down nearby offices.

Two Hanford workers have tested positive for radioactive waste in their bodies. It happened at the Plutonium Finishing Plant—a massive factory being demolished at the nuclear cleanup site in southeast Washington state.

A new report about the radioactive tank waste at Hanford says the cleanup could take decades longer and cost billions more than estimated. The document, called “System Plan 8”, proposes 11 complex scenarios for how the 56 million gallons of radioactive tank waste could be moved out of those tanks and treated.

The U.S. Department of Energy is about start shoring up another train tunnel full of old radioactive equipment at the Hanford Site in southeast Washington state. This is all happening because a similar train tunnel full of waste—called Tunnel 1—collapsed this spring.

Back in May, a train tunnel at the Hanford nuclear site partially collapsed. Federal contractors have now just finished filling it up with grout. It took about 520 truck loads of grout to fill the tunnel.

At the Hanford Site in southeast Washington state, a powerful group of citizens who keep watch on the nuclear reservation hasn’t met in months. Northwest tribes, environmental watchdogs and nuclear cleanup experts all sit on the Hanford Advisory Board—nicknamed the HAB.

This spring, an underground train tunnel full of radioactive waste was discovered partially collapsed at the Hanford Site in southeast Washington state. Now, federal contractors are prepping the site to fill the unstable tunnel with grout. They’re planning to start Tuesday night.

Crews at the Hanford Site in southeast Washington state are running through rehearsals and last minute details. In early October, they’ll begin pouring grout, a kind of thin cement, into a partially collapsed tunnel full of highly contaminated radioactive waste.

Jeannie Yandel speaks with Northwest News Network reporter Anna King about the continued problem of cleaning up the Hanford Nuclear Reservation in Eastern Washington. The topic was in the news because John Oliver talked about the contaminated site on his satirical HBO show.

In the wake of a tunnel collapse at the Hanford nuclear site in May, the U.S. Department of Energy plans to take public comments at a meeting in the Tri-Cities on July 20 on how it should proceed with the clean-up.

Bill Radke talks to Anna King, a journalist with the Northwest News Network, about her reporting on the Hanford tunnel collapse, including why it happened and what it means for other nuclear waste storage sites at Hanford.

The Hanford nuclear reservation in southeast Washington state has two train tunnels full of very hot radioactive waste—and both tunnels are in danger of further collapse. That’s according to a new report commissioned by the U.S. Department of Energy.

About 90 minutes north of Stockholm lies an ancient defensive hillfort called Broborg. Northwest scientists are digging up and studying pieces of the ancient Swedish fort and trying to figure out how the structure has lasted around 2,000 years.

Over the weekend, workers at the Hanford nuclear site finished installing a thick plastic covering over train tunnel full of radioactive waste. The tunnel was found to have collapsed and opened up a hole nearly two weeks ago.
